Employers are no longer required to send the IRS copies of questionable W-4 withholding forms, effective April 14. In the past, employers had to send the IRS copies of Form W-4s for employees who claimed more than 10 allowances or those who claimed complete exemption from withholding and earned $200 or more in weekly wages.
The tax agency will still review W-4s, but employers no longer need to submit them to the IRS unless it asks for them. The IRS says it will use information already reported on W-2 forms to identify employees with withholding compliance problems. For details, see IRS release 2005-45 at www.irs.gov /newsroom.
